Day tank use – Instrument setup
:
If you are using a day tank you must set parameter 113 to off. This is the auto
zero. If this parameter is not turned off the instrument will zero out the reading as
the chemical is pumped in. If the instrument skips over P113 set P100 to USER
and P113 will appear in the menu. If parameter 213 is available set it to off as
well. See the
Changing Configuration Parameters
page for an example.
The operating mode of the EI1000 or 2000 should be set to fully manual (P001
set to 1).
Set the tare weight to 0. On a day tank application the gross and remaining will
show the same value.
All piping to the tank must have a flexible section to allow the scale and tank to
move. If any pipes are rigidly attached it will affect the accuracy of the scale.
Install a flexible section if needed. Do not allow the tank or scale to bear the
weight of any piping.
Unless the pumps can completely empty the tank, there will be some product left
in the bottom. This residual can be ignored. The weight will show how much
usable product is left in the tank.
The instrument can be calibrated to read in gallons instead of pounds if desired.
Make sure to clearly mark “Gallons” on the instrument face to avoid any
confusion if you do this.
On the LP4300 or any scale with four load cells you can place known weights on
the top of the tank to calibrate they system instead of adding product. Use
weights totaling at least 10% of the tanks capacity. This won’t work with the
LP4310 and LP4320.
If the display stays at zero when chemicals are pumped into the tank, double
check parameter P113 (auto zero) is OFF. A quick test is to put a weight
between 2 to 5 pounds on the scale. If the instrument goes to zero within 20
seconds this parameter is
on
. See the
Turn off Auto Zero
section.
